A variety of indene derivatives and disubstituted benzo[b]furans are readily prepared under the mild reaction condition from propargylic compounds by phase-transfer catalysis (PTC) instead of metal catalysis.

{A figure is presented}A variety of 2-aroyl(acyl, or carboxyl)-3-vinyl benzo[b]furans have been prepared via C-C bond formation in good to excellent yields by Pd/C-catalyzed cyclization/isomerization of propargylic compounds. The reaction proceeded with easily accessible starting materials and inexpensive catalyst under mild conditions. Furthermore, a number of benzo[b]furan derivatives including an allene functional group have been prepared too.
